In DGSD, the Janitor Monk famously "killed" (actually sent into a deep, death-like coma) Siu Yeun San and Mo Yung Bok; the Janitor Monk casually sent the two mighty warriors to death's door, then just as easily brought them back. This was a unique feat in the Jin Yong canon that is one of the prime examples of why the Janitor Monk is considered the supreme power in the Jin Yong wuxia universe.
What if the Janitor Monk had been present on Mt. Hua during ROCH on the day that North Beggar Hung 7 Gung and West Poison Au Yeung Fung killed each other? If the Janitor Monk were there just moments before Hung 7 Gung and Au Yeung Fung took their last breaths, could he have saved their lives with his incredible powers?
